If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

Omeprazole Ref PHR1059-1G I noticed in the purity calculation formula that both loss on drying (LoD) and water content are taken into account. What is the reason for that, knowing LoD also allows to measure water content ?
1 answer-
The Loss On Drying (LOD) testing for this product is performed at 60°C, as required by the current monograph for determination of volatiles. This temperature is not high enough to determine the entire water content.

What is the solubility of product PHR1059 (CAS 73590-58-6)? Specifically, is it soluble in methanol?
1 answer-
Solubility testing for this product has not been conducted. There is no data available regarding solubility in methanol for this product or related products with the same CAS 73590-58-6. However, for omeprazole product O104 (CAS 73590-58-6), the solubility is as follows: H2O: 0.5 mg/mL, DMSO: >19 mg/mL, ethanol: 4.5 mg/mL.
